PROCESS FOR THE MANUFACTURE 0F RUBBER SUBSTITUTE.

Specification of Letters Patent. Application filed March 20, 1909. Serial No. 484,738.

' Patented Oct. 1'7, 1911.

To all whom it may concern:

Be it known that I, NICOLAUS Rnrr, a subject of the Emperor of Germany, and resident of Hanover, Germany, have invented certain new and useful Improvements in Processes for the Manufacture of Rubber Substitute, of which the following. is a specification.

This invention relates to the manufacture of chemical products and has for its chief object to combine substances capable of readily reacting to form solid bodies in continuo-usly measured quantities, and in such a manner that the final product is obtained directly in a granulated,powdered, flaked or similar condition.

According to this invention the substances are supplied to a mixing apparatus for the purpose of obtaining a' chemical reaction the said substances issuing from the. apparatus with a rotary movement and reacting during the said movement to become converted into fine grains, powder or flakes. -By means of this process, costly disintegrating operations, poisonous eii'ects and loss'of material are avoided, while the products obtained are more uniform, as hereinafter demonstrated by Way of, example in connection with the manufacture of linseed oil india rubber.

In order that the said invention may be clearly understood and readily carried into effect the same will be described more fully with reference to the accompanying drawings in which Figure l is an elevation partly in section, and Fig. 2 is a plan of one convenient form of apparatus. Fig. 3 is a horizontal section on the line AB and Fig. 4 is a horizontal section on the line CD of Fig. 1. Fig. 5 is a sectional elevation of a modified construction and Fig. '6 is a section on the line EF of Fig. 5.

Linseed 011' india rubber is at present pro duced in a very dangerous manner by mixing oil with sulfur monochlorid, the product being in the form of large lumps which are round and washed with alkaline solutions or the purpose of neutralizing.

Linseed oil india rubber is obtained in the following manner by the present process. Sulfur monochlorid enters the mouthpiece b of the apparatus through the pipe 2' and the passage l formed in the cover plate f (Fig. 5). Simultaneously oil under high pressure in measured quantities enters the Worm 0 through the pipe g, mingles in the and during the reactic'i leaves the outlet at with a rotary movement, thereby becoming pulverized and precipitated as linseed oil india rubber in the form of flakes. Through. the pipe m '(Fig. 1) an alkaline washing liquid cooled to a very low temperature is simultaneouslymonducted to the rotating mass so that owing to the cooling the formation of hydrochloric acid ,is minimized and any acid which may be produced is neutralized. As this operation takes place'automatically, and can be carried into practice in hermeticall'y'closed apparatus, the present process eliminates all the difiiculties and dismouthpiece b with the sulfur monochlorid advantages of the known methods of manufacturing linseed oil india rubber.

In order to regulate the quantity of liquid conducted through the pipe g, without producing a reduction of the pressure in the casing a, the cover plate 7 is clamped. in position between the casing a. and the mouthpiece b. If the worm c, which is rotatable with the pipe 9, is obturated by the cover plate f either Wholly or partially, the quantity of liquid passing can be regulated within wide limits without altering the working pressure. With the worm a fully open and the pipe 9 rotating quickly the apparatus can also be efl'ectively and automatically cleaned.

If in the construction illustrated in Fig. 5 the passages Z be omitted and the point of the cover plate be drilled through at 70, the substance which enters through the pipe z' passes through the outlet at in a smooth jet and is there seized by the rotating liquid issuing from the worm c and granulated with it, this aifording adequate mixing in certain cases.

Claims:

1. The'process of manufacturing chemical products consisting of mixing the components of the product in a suitable mixing apparatus, causin the said components thus mixed to emerge rom the mixing apparatus with a rotary movement and causing said components to react during the said rotarymovement; and simultaneously therewith subjecting the same to a conditioning element.

2. The process of manufacturing chemical products, which consists in mixing the com ponents of the product in a suitable mixing apparatus, expressing the mixed components from said mixing apparatus with a rotary movement, causing the'components to react during the said rotary movement, and simultaneously therewith subjecting the same to a conditioning element, and reducing the mixture to flake like condition. y 3. The process of manufacturing chemical products consisting of mixing the com ponents of the product in a suit-able mixing apparatus,'expressing the mixed components from said mixing apparatus with a rotary movement, and simultaneously therewith subjecting the same to a neutralizing element and reducing the mixture to flake like condition.

4. The process of manufacturing rubber substitute consisting of mixing the components of the product in a suitable mixing apparatus, expressing the mixed components from said mixing apparatus with a rotary movement and in tubular form and causing the same to react, and simultaneously therewith subjecting the same to a finely divided neutralizing substance to reduce the mixture to flake-like condition.

5. The process for the manufacture of rubber substitute consisting in mixing sulfur mono-chlorid with oil under high pressure in a suitable mixing apparatus, causing 6. The process for the manufacture of lin-.

seed oil india rubber consisting in mixing sulfur mono-chlorid wit-h oil under high pressure in a suitable mixing apparatus, causing said elements thus mixed to escape with a rotary movement and causing the same to react, and finally subjecting the same to a neutralizing agent consisting of an alkali to reduce the mixture to flake-like condition.

The foregoing specification signed at Hanover; Germany, this eighth day of February, 1909.
